“Our device is the first implementation of the absorption refrigeration cycle on the nanoscale,” said a CQT researcher.

It isn’t exactly the way they created this quantum fridge that intrigues us but its use.

What such an invisible cooling device is good for? Quantum thermodynamics.

“Studying such small devices is important to see how thermodynamics – our best understanding of heat flows – may need tweaking to reflect more fundamental laws. The principles of thermodynamics are based on the average behaviors of big systems. They don’t take quantum effects into account, which matters for scientists building nanomachines and quantum devices.”

Authors of the paper, published in Nature Communications, raise some interesting perspectives like the possibility of using quantum correlations as a fuel.
